Abstract (en)

[origin: US4677189A] Disclosed are lactam polymerization initiators comprising at least two lactam terminal groups of the formula: <IMAGE> wherein Q is a lactam residue containing a C3 to C11 alkylene group and is bonded to a carbonyl through the nitrogen atom of the lactam; A is an aliphatic or aromatic hydrocarbyl or hydrocarbyl ether group; m is 0 or 1; when m is 0, n is 0 or 1 and p is 1; when m is 1, n is in the range of 1 to 3 and p=n; and an elastomeric backbone derived from a telechelic polyamine containing at least two primary or secondary amine groups. Also disclosed are a process for forming the same; nylon block copolymers produced therefrom; and a process for the polymerization thereof.
